福海站蒸发量变化特征及影响因子分析

Evaporation Variation Characteristics and Influencing Factors in Fuhai Station

以乌伦古河流域福海水文站为例,基于测站蒸发量、日照时数、气温、风速、水汽压等气象资料,进行了1970—2020年间测站蒸发量变化趋势及相关气象因子影响程度的量化分析与比较研究。结果表明,福海站蒸发量时间变化特征明显,且在时间序列中春季和夏季蒸发量无明显变化、秋季和冬季蒸发量明显增大;就影响测站蒸发量的气象因子而言,日照时数、风速和水汽压具有增大蒸发量的作用,而气温则具有减少蒸发量的作用。

Taking the Fuhai Hydrological Station in the Ulungu River basin as an example,this paper has carried on a quantitative analysis and a comparison research of the station evaporation change tendency and the related meteorological factor influence degree from 1970 to 2020 according to the meteorological data of evaporation,sunshine hours,temperature,wind speed,water vapor pressure and so on.The results show that the temporal variation of evaporation in Fuhai Station is obvious,and in the time series,the evaporation in spring and summer did not change significantly,while the evaporation in autumn and winter increased significantly.In terms of meteorological factors affecting evaporation,sunshine hours,wind speed and water vapor pressure can increase evaporation,while temperature can reduce evaporation.
